Answer:

1/3 + a = 5/4

To find the value of a, we isolate a by applying inverse operations.

So the inverse operation of addition is subtraction, we subtract 1/3 from both sides;

-1/3         -1/3

a = 11/12

Answer:

a = 11/12

Step-by-step explanation:

Start by isolating "a" by subtracting 1/3 from the left and right sides.

a = 5/4 - 1/3

In order to combine the fractions, we need to find the lowest common denominator. That means the lowest number that is divisible by both 4 and 3. In this case, the lowest common denominator is 12.

So 5/4 becomes 15/12 and 1/3 becomes 4/12. 15/12 - 4/12 = 11/12

a = 11/12
